For example, in the case of a milling cutter, the milling head to which the indexable inserts are firmly attached is set in rotation for machining and the rotating cutting edge is brought into contact with the workpiece to be machined.
- indexable inserts with several cutting edges is that as soon as a cutting edge wears out and has become unusable, the cutting plate can be rotated or flipped over after loosening a clamping device and a new cutting edge can be used.

Due to the wide range of possible applications and the associated specific geometry requirements, there is a need for a large number of different indexable inserts. This is particularly problematic with regard to the storage of spare parts because a corresponding number of different indexable inserts must be kept ready in order to make them available on the market quickly.
